A resin composition comprises (1) a thermoplastic resin and (2) a modified polyacetal wherein a residue of a polymerizable compound having a functional group such as an epoxy group, a carboxyl group, an acid anhydride group or others is introduced to a base polyacetal in a proportion of 0.1 to 30% by weight relative to the base polyacetal. The thermoplastic resin includes various polymers such as an olefinic polymer, a styrenic polymer, a polyester, a polyamide and so on. The thermoplastic resins can be used singly or in combination, and the latter combination includes a combination of two or more species of resins being immiscible with each other, a combination of a polyacetal and a resin except for a polyacetal (e.g. an elastomer, etc.) and other combinations. The relative ratio of (1) the thermoplastic resin to (2) the modified polyacetal is such that the former/the latter equals about 1/99 through 99/1 (by weight).
一种树脂组合物包括(1)热塑性树脂和(2)改性聚缩醛,在改性聚缩醛中,具有环氧基、羧基、酸酐基等官能团的可聚合化合物的残留物以 0.1%至 30%(按重量计)的比例加入到基聚缩醛中。热塑性树脂包括各种聚合物,如烯烃聚合物、苯乙烯聚合物、聚酯、聚酰胺等。热塑性树脂可以单独使用,也可以组合使用,后者包括两种或两种以上互不相溶的树脂的组合、聚缩醛和除聚缩醛以外的树脂(如弹性体等)的组合以及其他组合。(1)热塑性树脂与(2)改性聚缩醛的相对比例为前者/后者等于约 1/99 至 99/1(重量比)。
